Vikunja: Plaintext storage of password-reset/email-confirm tokens in database enables account takeover on DB read access

CVSS 8.1 EPSS <1%Fix available

[ Why it matters ]Priority signals

  • Public proof-of-concept exploit exists (CISA SSVC)

[ Description ]Official description

Vikunja is an open-source self-hosted task management platform. Versions prior to 2.4.0 store password-reset, email-confirmation, and account-deletion tokens in the `user_tokens` table in plaintext. If an attacker gains read access to the database through a backup leak, misconfigured storage, or SQL-level exposure, they can immediately use pending tokens to take over user accounts without knowing passwords. Version 2.4.0 fixes the issue.
